SPECIFICATION forming part of Letters Patent No. seen'saa tea February12, 1895.

Application filed August 16,1894. Serial No. 620,496. (llo model.) 7

as ships hulls,'decks, deck-houses, bulkheads, tanks, &c.; pontons,caissons, liquid and gas holders or containers wherein plating issecured to frames; and other like or analogous structures wherein platesof iron or, steel or other metal are employed in connection with framesor frame work, and fastened to them as well as together. The inventionhas mainly for its object toprovide improvements in plated structures bywhich the weight of such structures, and also the cost of same, isdiminished.

The invention will be described, for convenience, as applied to shipshulls.

According to this invention, theuse of filling strips, usually employedbetween some of the platings or strakes, of the hull and the frames, isobviated, and without alteration of the ordinary form or construction ofsuch frames, all the plates being by it caused to come in contact withor against the frames. The horizontal meeting edges of the plates whichoverlap each other, are turned the one in and the other out, and theparts of the inwardly turned edges of the plate where they come incontact with the frames, are cut away at the inside in such amanner thatthe inside surface of the plate lies evenly on the frame throughout. Theplates may be riveted or fastened together and to the frames in theusual or any suitable way.

The invention may be applied to ships having the plating or strakesarranged accord-: ing to the clinker mode of building, or to theordinary mode.

The above description of the invention as applied to the hull of a shipis suitable to other plated parts of ships, and other plated structures,having the characteristics above referred to.

In the drawings illustrating this-invention,

I show the invention applied ,to an iron or steel ship.

In the drawings, Figure 1 is a cross section showing the inventionapplied to the side plating of the ship, and also to a deck, the platingof the ships side being of the clinker side plates, and b are theframes, which are of ordinary, construction being straight or even ontheir outer surface. The plates, with longitudinal joints, as will beseen by the drawings, at their meeting edges overlap each other, and areturned, the one inward, and the other out. The parts of the inwardlyturned edges where they come opposite to and in contact with the framesare cut away, making channels 0 in the edges of the plates, the channelsbeing so out that the surface of the plate from edge to edge at theseparts (that is, where they come opposite the frames) are eventhroughout, and lie evenly on the frames 12; andat the same time, admitof the inner surface of the adjacent plate lying on the frame bar evenlyfrom the edge of the cut away plate to the next joint. A section of theplate taken through the cut away parts, that is, channels 0, isillustrated by the dotted lines in-Fig. 5. Thus, the whole set ofstrakes or plates in the ship, constructed as shown, throughout thelength of the frame come in contact with the plates and the eifectsabove stated are thereby obtained.

In a clinker built vessel, as shown in Fig. 1, each plate will have oneedge bent inword and the other outward, the inwardly turned edge havingthe cut away portion or channels 0 provided in it; while in a vesselwith the ordinary arrangement or form of plating shown in Figs. 2, 3, 4,and 5, the different rows of plating are differently formed andconstructed; namely, the successive strakes or rows of plating have boththeir edges turned outwardly and inwardly, re-' spectively. Thus theseplates alone having the inwardly turned edges are provided with the cutaway portions or channels 0. The deck plating and structure is preciselysimilar to the side plating. The plates in this case- Fig. 1-aredesignated d, and the deck beam 6, the edges of the plates at the jointbeing bent inwardly and outwardly as shown, and the inwardly turnededges being cut away in exactly the same manner as set forth withreference to the side plating.

Having fully described and shown by drawings my invention as applied toships, its application to other plated structures, such as thosehereinbefore specified, will be understood to be those connected withthe construction of plated structures without further description.

What is claimed in respect of this invention is In plated structures,such as navigable vessels, pontons and the like, the combina tion withthe frames or beams, of rows or strakes of plating connected by lapjoints in which the overlapping edges of the plates are bent away fromeach other, the one inward and the other outward, and the said inwardlyturned edges of the plates cut away to form channels 0 to receive theframes or beams and permit the inner surfaces of all the plates to comein close and even contact with said frames or beams, as shown anddescribed.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.

WILLIAM STEWART.
